Environmental And Edaphic Effects On Western Corn Rootworm (Coleoptera: Chrysomelidae) Overwintering Egg Survival, L. D. Godfrey, Lance J. Meinke, Robert J. Wright, Gary L. Hein

Department of Entomology: Faculty Publications

Western corn rootworm, Diabrotica virgifera virgifera LeConte, overwintering egg survival was studied at 3 soil depths (7.5, 15, and 30 cm), 3 soil textures (silty clay loam, loam, and sandy loam), and 2 surface residue treatments (with and without surface cover) at an eastern Nebraska site in 1989-1990 and 1990-1991. At a western Nebraska site, egg survival was evaluated at 3 soil depths (7.5, 15, and 30 cm), 2 surface residue regimes (with and without surface cover) within a fine sandy loam soil in 1989-1990. Overall, egg survival was low (30.0%) and intermediate (41.0%) at the eastern and western sites, …

Argentinoeme pseudobscura sp. nov., with 11-segmented antennae and appendiculate distal segment, constitutes the second known species of this genus.

Additions To The Known Range Of Bembidion Rufotinctum Chaudoir (Coleoptera: Carabidae: Bembidiini), Paul M. Choate, Angela L. Choate

Insecta Mundi

Previously known from northeastern United States and Virginia, Bembidion rufotinctum Chaudoir is recorded from North Carolina, Tennessee, South Carolina, and Georgia. Habitat preference for this species appears to remain the same throughout its range. Specimens may be found hiding in cracks in rocks exposed to rapidly flowing water. The presence of this species may be indicated by Pentacora ligata (Say)(Hemiptera: Saldidae) that occurs on the same rocks.

This species and S. luteicornis Parent are redescribed. Distinctions between Syntormonand Parasyntormon are discussed.

Occurrence Of The Milliped Ergodesmus Compactus Chamberlin In Canada (Polydesmida: Nearctodesmidae), Carl L. Whitney, Rowland M. Shelley

Insecta Mundi

Recent collecting in southcentral British Columbia, near the International Border, has confirmed the Canadian occurrence of the milliped Ergodesmus compactus Chamberlin, which was predicted by field work in the adjacent part of the United States. With Nearctodesmus insulanus (Chamberlin) occupying the Shuswap Highlands and the Pacific Coastal region, the Nearctodesmidae is known from three separate regions of Canada, all in British Columbia. Other millipeds in the northwestern United States that may be reasonably anticipated in western Canada are discussed.
